Question
Let
F = (3z + 3x²) i+ (6y + 4z + 4 sin(y²)) 3+ (3x + 4y + 6e²²) k
(a) Find curl F.
curl F = 0
(b) What does your answer to part (a) tell you about
SF. dr where C is the circle
(x − 15)² + (y – 10)² = 1 in the xy-plane, oriented
-
clockwise?
SoF. dr = 0
(c) If C is any closed curve, what can you say about
La F. dr?
SF. dr = 0
(d) Now let C be the half circle
-
(x − 15)² + (y − 10)² = 1 in the xy-plane with
y > 10, traversed from (16, 10) to (14, 10). Find
SF. dr by using your result from (c) and considering
C plus the line segment connecting the endpoints of C.
ScF·dr = 0
